JSArray<T extends JSAny?>
extension type
A JavaScript Array.
Because JSArray is an extension type, T is only a static guarantee and
the array does not necessarily only contain T elements. For example:
@JS()
external JSArray<JSNumber> get array;
array is not actually checked to ensure it contains instances of
JSNumber when called.
T may introduce additional checking elsewhere, however. When accessing
elements of JSArray with type T, there is a check to ensure the element
is a T to ensure soundness. Similarly, when converting to a List<T>,
casts may be introduced to ensure that it is indeed a List<T>.
